I loathe sexism, but of the two, I loathe feminism more than misogyny. Feminists seem to think that they are some sort of righteous crusader, while misogynists seem to know they are assholes.
It's simple folks. Equality. Equality means everyone is equal. No one gets left behind or forgotten.

implying that all feminists are extreme misandryans, nope, real feminists belive in equality, and have no problem with keeping some old traditions alive(men bringing flowers, pulling out chairs etc..) But they want equality in society, and especially in work related situations. etc, etc, etc...

Some people don't think it's fair that everyone gets the same.
When we talk about social equality, in this case, it is that everyone in the end have the same possibilities. In this sense, equality and justice are related terms.
The situation of the image illustrates the liberal and socialist views.

A customer went to the counter at a feminist bookstore. ¨Can you help me? I can't seem to find the humor section. The shop clerk replied, ¨Might I remind you that this is a feminist bookstore. There is no humor section.

My friend is a part of a feminist group, and wears that shirt.
The purpose of the shirt isn't to tell the world that she's a crazy activist.
The purpose is to say that not all feminists are crazy - the original idea behind feminism is sexual equality when the situation calls for it.. And that's what my friend stands for.
She hates the feminazis just as much as anyone else. But a true feminist wants true equality. That's what this shirt means.

I'm not going to make any judgements about this person and keep moving, because I don't know her.

Maybe she's a mother.
Maybe her grandad died of cancer a couple months ago.
Maybe she's single, but gets plenty of love from a good group of friends and family.
Maybe she's stupid, maybe she's smart.
Maybe she has a crazy fetish for plastic wedding cakes and shares numerous steamy lovemaking sessions with her plastic wedding cake fetishist husband
